The application of proton beams in radiation therapy and in diagnostic radiology is discussed. The development of techniques and apparatus to produce desired dose distributions is described, including beam broadening, broad beam collimation, range modulation, in-phantom dose measurements, a computer isodose program, treatment planning, and patient positioning apparatus. Initial demonstrations of high-contrast radiography using the proton beam were very encouraging. Human pathology specimens are being investigated to permit the prediction and interpretation of features that will be seen in proton radiography of patients. One patient with carcinoma of the breast was examined with proton radiography, the carcinoma was clearly distinguished from the normal tissues. Technical improvements to increase the range and reduce the dose are being studied. (GRA)
